Prepare for the 350-501 Implementing and Operating Cisco Service Provider Network Core Technologies exam with CertQueen's independently developed study resources. Review important concepts, practice scenario-based questions, and use clear explanations to identify areas that require further study.

Question#1

Why do Cisco MPLS TE tunnels require a link-state routing protocol?

A. Link-state routing protocols use SPF calculations that the tunnel endpoints leverage to implement the tunnel
B. The link-state database provides a data repository from which the tunnel endpoints can dynamically select a source ID
C. The tunnel endpoints can use the link-state database to evaluate the entire topology and determine the best path
D. The link state database provides segmentation by area, which improves the path-selection process

Explanation:
Cisco MPLS Traffic Engineering (TE) tunnels necessitate a link-state routing protocol like OSPF or IS-IS because these protocols use Shortest Path First (SPF) calculations. The tunnel endpoints leverage these SPF calculations to implement the tunnel, ensuring an efficient and optimized path through the network. This is essential for MPLS TE, which aims to optimize network resource utilization and improve traffic distribution across the network.

Question#2

Refer to the exhibit.



A Cisco engineer is implementing gRPC dial-out on an ASR. Receiver 192.168 1.1 will be assigned one of the subscriptions, and it will manage the ASR.
Which command is needed to complete the router configuration?

A. protocol grpc
B. protocol all
C. protocol tcp
D. protocol any

Explanation:
In this scenario, gRPC dial-out mode is being used for telemetry. The receiver with IP address 192.168.1.1 will be assigned one of the subscriptions and will manage the ASR. To configure this, the router needs to use the protocol tcp command. This ensures that telemetry data is streamed out over a TCP connection to the specified receiver. Other options (A, B, and D) are not relevant for this specific use case.

Question#3

A regional MPLS VPN provider operates m two regions and wants to provide MPLS L 3VPN service for a customer with two sites in these separate locations. The VPN provider approaches another organization to provide backbone carrier services so that the provider can connect to these two locations.
Which statement about this scenario is true?

A. When edge routers at different regional sites are connected over the global carrier backbone, MP-eBGP must run between the routers to exchange the customer VPNv4 routes
B. When eBGP is used for label exchange using the send label option, MPLS-BGP forwarding is configured under the global ABC CSC PE-to CE interface
C. When IGP is used for route exchange and LDP for label exchange, MPLS is enabled only on the VRF interface on the backbone-earner PE side.
D. When BGP is used for both route and label exchange, the neighbor a.b.c.d send-lable command is used under the address family VPNv4 command mode.

Explanation:
In this scenario, when edge routers at different regional sites are connected over a global carrier backbone, MP-eBGP must be run between routers to exchange customer VPNv4 routes. This is essential for enabling communication between customer sites located in different regions while utilizing a global carrier backbone service.

Question#4

The administrator of a small company network notices that intermittent network issues occasionally cause inbound notifications to its SNMP servers to be lost.
Which configuration must the administrator apply so that the SNMP servers acknowledge the notifications that they receive?

A. snmp-server community ciscotest rw 10
B. snmp-server host tests.cisco.com public snmp-server community ciscotest rw 10
C. snmp-server enable traps bgp snmp-server host 192.169.2.1 Informs
D. snmp-server enable traps snmp

Explanation:
The correct configuration to ensure that SNMP servers acknowledge the notifications they receive is to use the snmp-server host command with the Informs keyword. This configuration sends Inform requests instead of Trap messages. Unlike Traps, Inform requests are acknowledged by the receiving SNMP server, ensuring that the notification has been received. If an Inform request is not acknowledged, the SNMP agent resends the notification.
Reference: The information is based on the Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) training, which teaches how to configure, verify, troubleshoot, and optimize next-generation, Service Provider IP network infrastructures.

Question#5

An engineer is developing a configuration script to enable dial-out telemetry streams using gRPC on several new devices. TLS must be disabled on the devices.
Which configuration must the engineer apply on the network?

A. telemetry model-driven destination-group ciscotest address-family ipv4 192.168.1.0 port 57500 encoding self-describing-gpb protocol grpc no-tls commit
B. telemetry model-driven destination-group ciscotest address-family ipv4 192.168.1.0 port 57500 encoding self-describing-gpb protocol grpc commit
C. telemetry model-driven destination-group ciscotest address-family ipv4 192.168.1.0 port 57500 encoding self-describing-gpb protocol grpc tls-hostname ciscotest.com commit
D. telemetry model-driven destination-group DGroup1 address-family ipv4 172.0.0.0 port 5432 encoding self-describing-gpb protocol tcp commit

Explanation:
The configuration in Option A is correct for enabling dial-out telemetry streams using gRPC on devices with TLS disabled.
It uses model-driven telemetry (MDT), which is a new method of monitoring network devices. Unlike traditional methods that pull data from the device, MDT pushes data from the device to the collector.
In this configuration:
Telemetry is model-driven.
It specifies a destination group with an IP address and port number where the telemetry data will be sent.
The encoding is self-describing-gpb (Google Protocol Buffers).
The protocol used is TCP.
This setup ensures that telemetry data is sent to the specified collector without requiring TLS encryption.
